This Natural profile parameter can be used to assure that fields are marked / referenced correctly.
See also POS - Field Identification Function in the System Functions documentation.
| Possible settings | ON |
The old Version 2.2 algorithm will be used and the correct field will be marked/referenced Note: |
|---|---|---|
OFF |
The algorithm introduced with Natural Version 2.3 is used. | |
| Default setting | OFF |
|
| Dynamic specification | yes | |
| Specification within session | no |
As of Natural Version 2.3 for Mainframes, the internal algorithm for the
computation of the system function POS (internal field
identification) is different. As a result, if you execute with Version 2.3 or
higher programming objects which use the POS function in
conjunction with the MARK option of an
INPUT or
REINPUT statement or
with the system variable *CURS-FIELD and
which were compiled with Version 2.2 of the
Natural Optimizer
Compiler, the wrong field may be marked/referenced.
 |
Warning: This parameter will be available only for a limited period of time to allow you a smooth transition from Version 2.2. It will be removed again with a subsequent release of Natural. |
In a z/OS Parallel Sysplex environment, or if the Natural thread size
makes buffer reallocations necessary, POS22=ON cannot always be
guaranteed to yield the desired results. In these cases, the objects concerned
should be recataloged in the new version of the Natural Optimizer Compiler to
ensure correct POS result.
